路由控制器

一：自定义路由

原始方式：

from django.conf.urls import url
from app01 import views
urlpatterns = [
    url(r'^books/$', views.BookView.as_view()),
    url(r'^books/(?P<pk>\d+)$', views.BookDetailView.as_view()),
]

 

二：半自动路由

路由：

from django.conf.urls import url
from app01 import views
urlpatterns = [
    url(r'^publish/$', views.PublishView.as_view({'get':'list','post':'create'})),
    url(r'^publish/(?P<pk>\d+)/$', views.PublishView.as_view({'get':'retrieve','put':'update','delete':'destroy'})),
]

视图：继承ModelViewSet类或者ViewSetMixin类

from rest_framework.viewsets import ModelViewSet
class PublishView(ModelViewSet):
    queryset=models.Publish.objects.all()
    serializer_class=PublishSerializers

 

三：全自动路由

自动生成路由，很少用

路由：

from django.conf.urls import url,include
from app01 import views

from rest_framework import routers
router=routers.DefaultRouter()
router.register('publish',views.PublishView) # 两个参数，一个是匹配的路由，一个是视图中写的CBV的类


urlpatterns = [
    # http://127.0.0.1:8000/publish/format=json(渲染器通过这个判断，返回渲染的页面)
    # url(r'^publish/', views.PublishView.as_view({'get':'list','post':'create'})),
    # http://127.0.0.1:8000/publish.json(渲染器通过这个判断，返回渲染的页面)
    # url(r'^publish\.(?P<format>\w+)$', views.PublishView.as_view({'get':'list','post':'create'})),
    
    # 可以用 以下方式访问
    # 1 http://127.0.0.1:8000/publish/
    # 2 http://127.0.0.1:8000/publish.json
    # 3 http://127.0.0.1:8000/publish/3
    # 4 http://127.0.0.1:8000/publish/3.json   
    url(r'',include(router.urls))
]

视图：

from rest_framework.viewsets import ModelViewSet
class PublishView(ModelViewSet):
    queryset=models.Publish.objects.all()
    serializer_class=PublishSerializers1
